To convert 45000 inches into miles first you have to find out how much is miles to inches then divide you should 0.4500
Let me help you!!! ok, so remember, it is always easier when you are multiplying one fraction, and one decimal, to keep it simple, and make it either both decimals, or both fractions! so, for instance, i will change the 3/4 into a decimal:
*0.75
you get that by dividing the 3 by 4.
Now, you just divide the 0.75 x 29.2, which is (21.9) hope that helps!!!
F(x)=6x+57
F(18)=6x+57
F(18)=6(18)+57
F(18)=108+57
F(18)=165
1. D; -5m+2m, because -5+2=-3
2. B; 4 terms, every part of an expression that's not the subtraction/addition sign counts as a term.
3. Not 100% sure about this one, but I'll go with B; 4x².
4. C; 5b, that term cannot be combined because the variable is different from the rest.
I hope this was helpful.
General equation of the line is
y = mx + c
c = -3
m = 3
so the equation is
y = 3x - 3
